Wounds, Wound management and Drains Flashcards
a surgically created wound can be classified as:
a clean wound
a surgically created wound into the mucosa of the stomach is classified as:
a clean contaminated wound
a HBC with multiple lacerations comes in; we can classify these wounds as:
clean-contaminated wounds
an incision made into an abscess can be classified as:
a dirty wound
the most common source of operative wound infections is: a. you b. the operating room c. surgical instruments d. the patient
the patients endogenous flora
surgical site infection can occur within ____ days of surgery or up to ____ days with implants
30 days post op; 365 days (one year) with implants
T/F intraoperative administration of antibiotics when suspected contamination occurs during surgery or when surgery is longer than expected, has been shown to decrease incidence of infection.
False; while commonly done it has NOT been shown to decrease or increase incidence of infection
how does healing of superfical wounds differ in dogs and cats:
the SC plans an important role in healing for cats more than in dogs
what diagnostic tests would you consider before anesthetizing a dog that comes in from traumatic bite wounds?
rads! for pneumothorax baseline CBC/chem
what type of injury is this wound?
anatomic degloving injury
You have a patient with a draining tract from an old wound that seems to only heal while on antibiotics. How would you classify this wound and what can you do to make it heal properly?
non-healing wound; remove suspected foreign body
What is the best diagnostic tool to use to help us identify plant foreign bodies intra-op or before surgery?
ultrasound
what stain can you use in a tract prior to surgery to help locate a foreign body and follow the correct tract to the FB?
methylene blue stain
what is the “golden period”
time from injury til time from contamination and bacterial invasion of a wound
what type of particles inactive PMNS and can bind positively charged antibiotics, and thus can potentiate infection of wounds?
clays and organic soils*
be diligent about flushing these wounds
what is the first step when a traumatic wound patient enters your hospital?
a. assess neurological function
b. bandage wound
c. assess entire patient and perform PE
d. debride and clean wound
c. assess entire patient and perform PE
up to ___% of bacteria can be removed with wound lavage
a. 100%
b. 90%
c. 80%
d. 70%
b. 90%
what time of solution would you use for wound lavage on a granulating wound
a. tap water
b. saline
c. chlorohexidine and sterile water
d. chlorohexadine and sterile saline
b. saline
what is the residual activity of a povidone-iodine lavage solution?
4-6 hours
what is the debriding agent in granulex chemical debridement?
trypsin
which of the following is an example of mechanical debridement:
a. wound lavage with saline on a wound filled with granulation tissue
b. application of honey for a wound on a limb to be bandaged
using the primary layer of a bandage to soak up exudate and tissue
using the primary layer of a bandage to soak up exudate and tissue
what kind of dressing would you use for an early wound like this?
a. wet-dry aderent dressing
b. dry-dry adherent dressing
c. porous-non/low adherent dressing
d. no wound dressing
a. wet-dry aderent dressing
what kind of wounds would an immediate closure be indicated?
clean wounds and some clean contaminated wounds
how would you classify this surgical closure?
primary closure
a wound that was left open for a couple of days to allow epeated debridment then sutured closed later would be classified as:
delayed primary closure
a wound closure after granulation tissue has been allowed to cover the would would be classified as:
secondary closure
what kind of stitch is this?
ford interlocking
in which kind of closure or healing would you see contraction and epithelialization?
second intention healing
T/F you should try to make incision lines or wound closures parallel to skin tension lines of possible because they heal faster, are more aesthetic, and gape less
true
T/F when undermining skin you should undermine below the cutaneous trunci muscle using blunt dissection
true
what kind of suture patterns would you use with stents used to distribute pressure on skin
mattress sutures
what method was utilized here to help close the lesion?
what type of suture pattern was used?
multiple punctate relazing incisions; intradermal suture pattern
